CNBC's September 21 afternoon note attributes Monday's rally to two things. Oil fell hard — WTI down more than 5% to about $95 and Brent about 4% to just under $100 — after President Trump said he is open to talks with Iranian President Pezeshkian at the UN General Assembly and the New York Times reported he had held off striking the Houthis. And semiconductors split by CPU exposure: Intel up about 13% intraday, AMD about 9% while touching a $1 trillion market value, Arm more than 15%, Qualcomm about 8%, against Nvidia and Broadcom up 2% and 1%. CNBC ties the CPU bid to Meta's Muse agent app reaching No. 1 on Apple's App Store, which put agentic demand for supply-constrained CPUs back in focus; a Bernstein analyst is quoted on broad consumer agent adoption. The intraday figures are CNBC's; settled closes come from the tape.
